The Longest Journey is actually considered by many adventure fans as one of the best ever made - you are not talking about a good game, you are talking about something that stands as the top of the genre.
Not only is the story and setting detailed enough to be part of a novelised fantasy setting but it is a wonderful misc of sci-fi and fantasy. Amazing music and great puzzles but most importantly, the character April Ryan is the most realistic computer game character I have ever seen in terms of her reactions etc.. you almost believe she is alive later in the game.
Something NO adventure fan cam miss out on. The sequel is out soon....
